    In doing some research, I noticed the phone is set to global mode by default. Then digging some more, I noticed that cell standby was 70 percent after today's work.

    I have had the MAXX for a while now and cell standby has never been that high. Makes me wonder if the change in the radio is the possible culprit to this battery issue.

    I already changed it back over to LTE/CDMA in Settings. Washington State has superb LTE, so that's not the issue.

    I'm just wondering, for all of the other people who are having issues, if the global setting is the battery eater. Since I have the MAXX it's not really a fair test.

    I haven't had a regular usage day since I upgraded to ICS, but it really seems like my battery dies way too fast. Today 6hrs and 28min of battery usage left me with 20% battery left. This is a RAZR MAXX, but I've been on it constantly since I updated about 4 days ago.

    Gonna have to find some settings to save battery life.

    I actually use 4G all the time now. It doesn't drain my battery as much as it used to as soon as I found out the location services take up WAY more battery.

    Yea...I still havent found anything concrete or definite saying if global drains the battery more for us in the US. I remember something about it with the Droid 2 Global tho...and now I cant find it....lol. I spend most of my time in a weak reception area....it might be hard for me to tell anything.

    What I do notice is on Global....my data speeds are slower...and in areas with no signal...I got prompted for putting the phone on Global.

    Update:

    So after setting it to LTE/CDMA, the battery appears to have stabilized itself. Cell standby/Time without a signal has dropped down to a more respectable 26% (which appears to be an overall average).

    piggybacking off of what AndroidKachi7 said...I wonder if the "Global" setting is making more heavy use of Location Services in order to find global signals, thus draining the battery at a more rapid rate.

    What I plan to do is powercycle the phone before I put it on the dock tonight. With the "Global" setting off it makes my phone basically what it was when I installed the ICS leak. Then I'll run with my normal usage tomorrow and see what the dropoff is. I usually stream music at work which results in a roughly ~13-15 hours of battery. If I get that then I know I'm back to normal...and I'll see if "time without a signal" is in the normal range which is less than 10%.

    I have to also "hack" the Motorola Task Manager back into ICS somehow, just haven't had time, but now that I know how to do it I have to get working on that.

    First few days on ICS (soak) were not nearly as good as I used to get on GB. I let it run down to 30% the other day and then turned it off to charge when I went to bed. Both Sunday and yesterday were outstanding on battery. I was unplugged from 3am til 10pm and turned it off with 70% still showing on the battery indicator.

    So, if things aren't as good as you think, try turning it off before you charge as well as giving it a few days to "settle in".

    +1 ^^^ So much of what people report as bad battery results are related to charging with power on. Charging with power off allows the battery to achieve a true 100% full saturation charge and also sets the full battery flag to the proper voltage levels so the meter can properly reflect the remaining charge. Draining to 15% sets the low battery flag so the meter can properly know when the battery is near depletion and to signal the proper time to recharge.

    I understand, and here it comes, you knew it was coming,...."But", Ha Ha, there it is, what about us folks who only have our cell for communication because we don't have a land line anymore due to the high costs in our area? It's hard to turn the phone off to charge it when you have children that haven't come home yet or sick relatives that, well you know. I guess we just have to deal with it.

    I have just a razr and really haven't noticed any issues with the battery life after the upgrade, I get about a full day or so from it, and I'm always messing with it, so I'm not sure if my phone is just a freak of nature or I just have my settings all just right, but I'm see'ing no significant changes.

    So are you saying that if I only charge overnight I should shut down completely every night and charge that way? It's strange because I did that last night and my battery has been much better today.

    You only need to follow Professor FoxKat's recommendations once every two or three months, not every time you charge your phone. I don't know the specifics of your situation, but I would think anyone could do without their phone for 4 or 5 hours once in a while.

    Dr Foxcat sir I have a question.....
    I side loaded and I have been following all of your excellent advice on charging....but yesterday even though I was not experiencing glitches I decided to do a factory reset just because I didn't before side loading.... I noticed that my battery is not doing as well today as it was before.... I assume because I didn't take it down to 15% before charging last nite... would this be because when I did the reset it erased my battery's settings that it had saved from when I did the cycling?

    So by doing this, will it just me on CDMA/LTE or will it be just on CDMA? I am trying to figure out how to turn off global and have it on 3g/4g only to see if killing off the global helps my battery life bc my battery life sucks and im hoping that this will help

    UPDATE:

    So here's what I did.
    • Phone was fully charged. I took it off and did a powercycle then plugged it in while I got ready for work.
    • Took it off the charger at around 7am.
    • Mobile network was set to "LTE/CDMA" not "Global".
    • Didn't use it all the way to work but I was fully 4G connected the entire way, full GPS and location, Bluetooth enabled, WiFi enabled (but connected to nothing), etc. Screen stayed off.
    • Got to work and had it streaming Bluetooth the entire time. Didn't connect it to USB at all. Screen was off during streaming.
    • The stream stopped a couple of times but that looks like Motocast's Internet Radio failing as I was able to stream Amazon MP3 just fine.
    Roughly 13-ish hours later, I am at 10% remaining. This is well within expectations given the music streaming over 4G all day - for some reason that just kills the battery. I need to find a more energy efficient stream app, I think Motocast is a battery hog. Anyway...

    Checked Cell standby, after 13 hours the "Time without a signal" is 0%. That pretty much confirms the Global setting was causing signal issues at least in my area. Since I don't go international I can safely leave it off.

    Just sharing this for others to consider disabling that setting to see if it helps. It definitely helped here. The MAXX is back in action.
